Target Applications
Target applications for the TLE496x Hall switch family are all applications which require a high precision Hall
switch with an operating temperature range from -40°C to 170°C. Its superior supply voltage range from 3.0 V to
32 V with overvoltage capability (e.g. load-dump) up to 42 V without external resistor makes it ideally suited for
automotive and industrial applications.
The TLE4964-1M is a unipolar switch with a typical operating point B_OP = 18 mT and a hysteresis of B_HYS = 5.5 mT.
It is ideally suited for various position detection applications.
